Question

The diagonal of the rectangle is square root of 73. If the width is equals to 3cm, what is the area of the rectangle?

Answer 1

Answer:

AREA OF THE RECTANGLE IS 24cm²

Step-by-step explanation:

PARAMETERS GIVEN,

LENGTH OF THE DIAGONAL = √73

WIDTH OF THE RECTANGLE = 3cm

SO,

LET THE LENGTH OF THE RECTANGLE BE x

SO,

BY APPLYING PYTHAGORAS THEOREM,

WE GET,

(P)²+(B)² = (H)²

(x)²+(3) = (√73)²

x²+9=73

x² = 73-9

x² = 64

x = √64

x = 8cm

SO,

LENGTH OF THE RECTANGLE IS 8cm

SO,

WE KNOW,

AREA = LENGTH*BREDTH

          = 8cm*3cm

          = 24cm²

SO,

AREA OF THE RECTANGLE IS 24cm²

I HOPE YOU UNDERSTOOD THE QUESTION!!!
