Answer 1

Answer:

Step-by-step explanation:

Perimeter is 56m

TO FIND:- Length and Breadth if sides

SOLUTION

Perimeter = 2(Length + Breadth)

=> 56 = 2 ( 2x - 5 + x)

=> 28 = 3x - 5

=> 3x = 28 + 5

=> 3x = 33

=> x = 11

Now we got value of x i.e. breadth which is equals to 11m.

Hence Length = 2x - 5

= 2 × 11 - 5

= 22 - 5

= 17m

Therefore Length and breadth of rectangle are 17m and 11m respectively

Answer 2

Answer:

let the third side = x

two equal sides are 2x - 5, 2x - 5

perimeter = sum of all sides = 55 m

i.e. x + 2x - 5 + 2x - 5 = 55

5x - 10 = 55

5x = 55 + 10

5x = 65

x = 13

two equal sides = 2x - 5 = 2 × 13 - 5 = 26 - 5 = 21

thus, the lengths of three sides are 13 cm , 21 m and 21 m
