Question

The length of a rectangle is 7/5 of its breadth. If its perimeter is 48 CM so what is its length​

Answer 1

Answer:

Let the breadth of rectangle be 'x'

Length of rectangle=7/5 multiply x

Perimeter=2(length+breadth)

48=2(7x/5 + x)

48=14x/5 + x

48x5=14x+x

240=15x

240/15=x

Hence, x, ie, length=16

Hope it helps you!!!!

Answer 2

Step-by-step explanation:

• Lets take L = 7x/5
• Lets take breath x

Formulae For Permimeter

P = 2(L + B)

• 48 = 2(7x/5 + x)
• 48 = 14x/5 + 2x
• 240 = 14x + 2x
• 240 = 16x
• x = 240/16
• x = 15
