Answer:
300
Step-by-step explanation:
![\frac{Part}{Whole} = \frac{Percent}{100}](https://tex.z-dn.net/?f=%5Cfrac%7BPart%7D%7BWhole%7D%20%3D%20%5Cfrac%7BPercent%7D%7B100%7D)
![\frac{210}{x} =\frac{70}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B210%7D%7Bx%7D%20%3D%5Cfrac%7B70%7D%7B100%7D)
210(100) divided by 70 = 300
Answer:
Width is 20cm
Step-by-step explanation:
Step one:
Given data
let the width be x
W= x
L= x+5
P= 90
Step two:
The expression for the perimeter is
P= 2L+2W
90= 2*x+2(x+5)
90= 2x+2x+10
collect like terms
90-10=4x
80= 4x
divide both sides by 4
x= 80/4
x= 20
