Question

A rectangle measures 8cm on its length it's diagonal is 10cm.what is the perimeter of the rectangle.explain this in process​

Answer 1

Answer:

Perimeter of rectangle = (10) ²-(8) ²+b

=100-64=36

b= 36cm

b=6cm

perimeter = 2(l+b)

2(8+6) =28 cm

Step-by-step explanation:

Answer 2

Answer:

length = 8

daigonal = 10

(10) - ( 8) + bredth( we have to find the sqaure of given no. )

100 - 64 = 36

sqaure of 36 = 6 so the breadth is 6

perimeter of rectangle = 2 ( l + b )

2× 8+6

= 2× 14

28 is our perimeter of rectangle
