The width of a rectangle is 8 cm and the diagonal is 17 cm.Find the area of the rectangle.
A: 120
B: 15
C: 225
D: 136
since we only have the diagonal and the width of the rectangle, we have to use the Pythagoras Theorem to find its length/base;
To find the base , we apply the formulae below;
b² = hy² - h²
where b = base/length , hy = hypoteneus and h = height of the rectangle
hy = 17 cm
h = 8 cm
b² = 17² - 8²
b² = 289 - 64
b² = 225
we now calculate the square root to find the base of the rectange
b = √225
b = 15
since we have the base /length , we apply the area formulae to get the area of the recatangle
Area = length * width
Area = 15 * 8
Area = 120² cm
