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:

100=64+b square

36=b square

6=b

Perimeter=2(l+b)

=2(8+6)

=2(14)

=28

Hope it helps

Answer 2

Answer:

28

Step-by-step explanation:

To find The perimeter, we need to find the breadth.

To find the breadth, we will use Pythagoras theorem

= (h)² = (l) ² × (b) ²

(10)²= (8) ² + b²

100 = 64 + b

b² = 100 - 64

b² = √36

b = 6

____________________

Perimeter of rectangle(P) =2 × (l+w)

Perimeter of rectangle(P) = 2 × ( 8 + 6)

Perimeter of rectangle(P) = 2 × 14

Perimeter of rectangle(P) = 28
