Question

The length and width of a rectangle are in the ratio 5:3. The perimeter of the rectangle is 32cm. Find the length and width.

Answer 1

use the unitary method...

add the parts in the ratio...

Parts = 5 + 3

and you know

perimeter = 2l + 2w

so 32 = 2( l + w)

or

16 = l + w

take the value of 16 and divide by the number of ratio parts...

then length = 5 x answer width = 3 x answer

Answer 2

32=5a*3a a=4 L=20 W = 12

Answer 3

so the length is 10 and the width is 6?

Answer 4

32 DIVIDE BY 8 = 4 so a = 4

Answer 5

8 is from 5 +3

Answer 6

@bRidingHoo sight problem is length = 20 and width = 12 the perimeter is 64

Answer 7

thats correct @Sunshine447
