Question

solve this question plz help me ​Class 4th​​

Answer 1

Answer :-

• Perimeter of 1st Rectangle = 18cm

• Perimeter of 2nd Rectangle = 280m

Given :-

• Length = 5cm and Breadth = 4cm

• Length = 80m and Breadth = 60m

To Find :-

• To Find the Perimeter of Rectangle.

Step By Step Solution :-

As we know ⤵

$\boxed{ \sf{ \green{Perimeter =2 ( Length + Breadth )}}}$

$\implies \sf \: Perimeter = 2(5 + 4) \\ \\ \implies \sf \: Perimeter = 2 \times 9 cm\\ \\ \implies \sf \: Perimeter = 18cm$

Therefore Perimeter of 1st Rectangle = 18cm

$\implies \sf \: Perimeter = 2(80 + 60) \\ \\ \implies \sf \:Perimeter = 2 \times 140m \\ \\ \implies \sf \: Perimeter = 280m$

Therefore Perimeter of 2nd Rectangle = 280m
