A row of plaques covers 120 square feet of space along a wall. If the plaques are 3 feet tall, what length of the wall do they cover?

Answers

Answer 1
Answer:

Answer:

40 feet of the wall will be covered.

Step-by-step explanation:

A row of plaques cover an area of 120 square feet of space on the wall.

Height of the plaques is 3 feet then we have to tell the length of the wall that will be covered.

Area of the wall covered by plaques = Length of Plaques × width of the plaques

120 = length × 3

length = 120 ÷ 3 = 40 feet.

Therefore plaques will cover 40 feet of the wall.
Answer 2
Answer: Simple,

120 divide it by 3 to get your length.

(120)/(3) =40

Thus, it covers 140 ft of the wall.

The surface area doesn't depend on the unit you use to describe it,
but the number in the description does.

Definition:                                  1 cm  =  10 mm

Square each side:                 (1 cm)²  =  (10 mm)²

                                        (1)² · (cm)²  =  (10)² · (mm)²

                                                1 cm²  =  100 mm²

So if the area is 100 cm² but you want to describe it in mm² instead,
the number will become bigger.
