QR = 16 units
Step-by-step explanation:
Given that ΔPQR is right with hypotenuse QR
We can apply Pythagoras' theorem to find QR
QR² = 8² + (8)²
= 64 + 192
= 256
Take the square root of both sides
QR = = 16 units
The width becomes 21 centimeters hope this helps:)
Perimeter = 2(W+L) = 80
W + L = 40
W = 4
L = 36
so length = 36 cm
