Question

the diagonal of a rectangle is 10 cm long and it is equal yo twice the length of the rectangle.find the area of the rectangle.​

Answer 1

Answer:

here is your solution

Step-by-step explanation:

D = √w²+ l²

10cm = √w²+ (5cm)²

(10cm)² =. w² + (5cm²)

100 = w² + 25

w²= 100-25

w²= 75

w= √75= 8.66

Now Area of rectangle = l×w

= 5×8.66= 43.3 cm²
