Question

4) Find the missing measurement using the

formula provided. Round your solution to
the nearest tenth.
Area = ( xw
7.8 in
? in
Area = 60.8 in?

Answer 1

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)
