Question

15. The hypotenuse of a rectangle is 5 cm and its length is 4 cm, find the area of
the rectangle.​

Answer 1

Answer:

given

b=5cm

l=4cm

the area of the rectangle =a=l×b

a=4×5=20CM

I Hope it helps to you

Answer 2

Answer:

12m^2

Step-by-step explanation:

hypotenuse of a rectangle=(length)^2+(breadth)^2

so,

(h)^2=(l)^2+(b)^2

(5m)^2=(4m)^2+(b)^2

(b)^2=(5m)^2-(4m)^2

(b)^2=25m^2-16m^2

(b)^2=9m^2

(b)=3m

area=4m*3m

       =12m^2
