Question

The area of the right-
angled triangle is
equal to the area of
the rectangle.
Work out the value of
x.

Answer 1

Answer:

x = 15 cm

Step-by-step explanation:

Triangle area:

$area = \frac{(20)(15)}{2} = \frac{300}{2} = 150 \: cm$

Then rectangle area:

$area = (10)(x) \\ 150 = 10x \\ x = \frac{150}{10} \\ x = 15 \: cm$
