Question

a] Give length of rectangle is 3 times its breath If the perimether is 32 cm find the lenth and breath?​

Answer 1

Answer:

Length of the rectangle is three times its breadth.

∴ Let, the breadth be x cm , then length 3x cm.

Given, perimeter is 32 cm.

We know, perimeter. = 2 ( length + breadth )

Hence, 2 (3x + x) = 32

or, 4 x = 16 ⇒x=4

Therefore, breadth is 4 cm. and length is 12 cm.

Answer 2

Step-by-step explanation:

let the breadth be b and length l

so l = 3b

perimeter of rectangle = 2(l+b)

2(l+b) = 32. (given)

l+b = 32/2

3b + b =16. (since l=3b)

4b = 16

b= 4

therefore length = 4*3=12cm

breadth = 4 cm
