Question

the length of a parallelogram is 25 cm and width is 20 cm find the perimeter shown with figure​

Answer 1

$\huge\text{\underline{Answer}}$

$\sf{\underline{Given }}$

From above pic in attachment:-

AB = DC = 25 cm

AC = BD = 20 cm

we know that the opposite side of a parallelogram is equal.

Then perimeter of parallelogram is = $\bold{2× (a + b)}$

put the value of a and b in formula

perimeter of parallelogram ABCD = $\bold{2× (25 + 20 ) }$

perimeter of parallelogram ABCD =

$\bold{2 × 45 = 90 cm }$

hence perimeter of parallelogram ABCD = 90 cm
