Question

the perimeter of a rectangle is 70 cm.if the ratio of the length to breadth is 3:2,find the dimensions​

Answer 1

Answer:

21 CM AND 14 CM

Step-by-step explanation:

LET L=3XANDB=2X

P OF RECTANGLE =2L+B

70=2*3X+2X

70/2=SX

35=5X

THEREFORE X= 7CM

NOW 3X=3*7=21CM

AND

2X=2*7=14 CM

Answer 2

Let the ratios be 2x and 3x.

2(l+b) = 70

2(2x+3x) = 70

2(5x) = 70

x = 7

Dimensions:

l = 3×7 = 21cm

b = 2×7 = 14 cm

Hope it helps! ♡
