Answer:
Step-by-step explanation:
Given the formula for calculating the area as;
A = xw
x is the length
w is the width
Given;
x = 7.8in
Area A = 60.8in²
Required
width w
Substitute the given parameters into the formula as shown;
! = xw
60.8 = 7.8w
divide both sides by 7.8
60.8/7.8 = 7.8/7.8w
7.795 = w
w = 7.8 in (to the nearest tenth)
