Question

the perimeter of the squares ⬛ abcd is twice the perimeter of the triangle ️ pqr .if the sides of the triangle are 21 cmm29cm,and 34cm,find the length of each side of the triangle ​

Answer 1

Answer:

the length of each side of the triangle is already given. if you wanted us to find the length of each side of square then it is 42 cm.

Step-by-step explanation:

perimeter of triangle=sum of all sides=21+29+34=84 cm

perimeter of the square=2*perimeter of triangle =2*84cm=168 cm

now side of square=perimeter/4=168 cm/4=42 cm

hence,

the answer is length of each side of the square is 42 cm.

pls mark me brainliest.

Answer 2

$\huge\underline{\red{Answer}}$

Given - Perimeter of square is twice the Perimeter of triangle

Sides of triangle = 21cm, 29cm , 34 cm

Perimeter of triangle = a+b+c

= 21+29+34

= 84cm

So Perimeter of square is twice the Perimeter of triangle

Therefore - 2×84

= 168cm

Perimeter of square = 168 cm

Perimeter of square = 4× side

According to condition = 4× side = 168

= side = 168/4

= 42cm

So each side of square is 42 cm.
