Question

1. The perimeter of a rectangle is 13 cm and width is 11/4 cm, find its length.
2. Find the square root of 12.25.​

Answer 1

1.) perimeter of rectangle = 13 cm

width = 11/4 cm

length = ?

A.T.Q.

perimeter = 2(L+B)

13 = 2(L+11/4)

13 = 2L + 11/2

13-11/2 = 2L

26-11/2 = 2L

15/2 = 2L

L = 15/2x2

L = 15/4

2.) 12.25

= √12.25

= 3.5

Answer 2

Answer:

(1) perimeter=13cm

width = 11/4cm

length = ?

Now, we know that the perimeter of rectangle is = p=2(l+b)

so, 13=2(l+11/4)

13 = 2l+11/2

13-11/2 =2l

15/2=2l

l=15/4

(2) square root of 12.25
