Question

Find the value of x :

a) In a rectangle, adjacent sides measure x + 2 and 2x - 3 and perimeter = 40 units. find x

Answer 1

side 1=x+2
side 2=2x-3
Perimeter=40 units
2(l+b)=40
l+b=20
x+2+2x-3=20
3x-1=20
3x=21
x=21/3
x=7

I hope it helps you

Answer 2

Answer:

Value of x = 7

Step-by-step explanation:

The perimeter of rectangle = 2(l+b)

2(x+2+2x-3) = 40

3x - 1 = 20

3x = 21

x = 7
