1. A contractor is preparing to lay out a rectangular concrete slab that
measures 48 feet in length and 36 feet in width. The project
specifications require that the contractor calculate the total square
footage of the slab in order to estimate material quantities and labor
costs accurately. What is the total area of the slab?
A. 1,248 square feet
B. 1,536 square feet
C. 1,728 square feet
D. 1,944 square feet
The area of a rectangle is calculated by multiplying length by width.
Multiplying 48 feet by 36 feet results in 1,728 square feet. Accurate area
calculations are essential in construction estimating and material ordering.
, 2. A carpenter needs to determine the perimeter of a rectangular
storage shed foundation measuring 22 feet long and 18 feet wide. The
perimeter must be known before ordering pressure-treated sill plates.
What is the total perimeter?
A. 80 feet
B. 72 feet
C. 96 feet
D. 40 feet
The perimeter of a rectangle equals 2 times the length plus 2 times the
width. Therefore, (22 × 2) + (18 × 2) equals 44 + 36, which totals 80 feet.
3. A concrete contractor must convert 5.5 yards into feet for a layout
measurement. Since one yard equals 3 feet, what is the equivalent
measurement in feet?
A. 14.5 feet
B. 15 feet
C. 16 feet
D. 16.5 feet
To convert yards into feet, multiply the yard measurement by 3.
Multiplying 5.5 by 3 gives 16.5 feet.
, 4. An electrician is calculating the total load on a branch circuit
containing three appliances rated at 8 amps, 12 amps, and 15 amps
respectively. What is the total amperage draw on the circuit?
A. 25 amps
B. 30 amps
C. 35 amps
D. 40 amps
Total electrical load is found by adding the amperage of all connected
devices. Adding 8, 12, and 15 equals 35 amps.
5. A roofer is estimating shingles for a roof section measuring 24 feet by
30 feet. Roofing materials are sold according to square footage
coverage. What is the area of this roof section?
A. 620 square feet
B. 680 square feet
C. 720 square feet
D. 840 square feet
Area is determined by multiplying length by width. Multiplying 24 feet by
30 feet results in 720 square feet.
6. A plumbing contractor purchases 12 lengths of pipe at $18.75 each.
What is the total cost before taxes?
, A. $200.00
B. $210.50
C. $225.00
D. $235.25
Multiply the quantity by the unit price. Twelve pipes multiplied by $18.75
equals $225.00.
7. A mason mixes concrete using a ratio of 1 part cement, 2 parts sand,
and 3 parts gravel. If the total mixture equals 60 cubic feet, how many
cubic feet of gravel are required?
A. 10 cubic feet
B. 15 cubic feet
C. 20 cubic feet
D. 30 cubic feet
The total ratio parts equal 6. Gravel represents 3 of the 6 parts, or one-half
of the total mixture. One-half of 60 cubic feet equals 30 cubic feet.
8. A framing contractor must determine the diagonal measurement of a
rectangular room that is 9 feet wide and 12 feet long. Using the
Pythagorean theorem, what is the diagonal distance?
A. 13 feet
B. 14 feet
