Question

The length of this rectangle is
three times as long as its width.
Find the length if the perimeter is
70.4 units.​

Answer 1

Step-by-step explanation:

let width be x

then length will be 3x

perimeter is 70.4

p=2×(l+ b)

70.4 = 2×(3x+x)

70.4 /2=4x

35.2=4x

35.2/4=x

8.8

the width is 8.8

length is 8.8×3= 35.2
