Question

the primeter of a rectangle is 13 CM and its width 2 3 upon 4 CM . find it's length​

Answer 1

A pleasure night freind,

Perimeter = 13 cm

Let the length be x cm

Width = 2whole 3 / 4

= 4*2 + 3 / 4

= 11 / 4 cm

Peimeter of rectangle = 2 ( l + b )

13 = 2 ( x + 11 / 4 )

13 = 2 / 4 ( 4x + 11 )

26 = 4x + 11

26 - 11 = 4x

15 / 4 = x

Therefore length = 15 / 4 cm or 3 3 / 4cm

Hope it helps

Answer 2

Answer:

3.75 cm.

Step-by-step explanation:

We have:

Perimeter of the rectangle = 13 cm

Width= 2$\frac{3}{4}$ cm = $\frac{11}{4}$ cm

let the measure of length be x

A/Q

2( 11/4 + x) = 13

=> 11/2 + 2x = 13

=> 2x = 13 - 11/2 = 15/2

=> x = 15/4 = 3$\frac{3}{4}$

Hence, length = 3.75 cm.
