Question

Here is a triangle with the height on the side of the triangle. Use the formula: (1/2)*(Base)*(Height) to find the area of the triangle at the left.​

Answer 1

(If one square on the graph = one centimeter)

b = 10cm

b = 10cmh = 10cm

Area:

$= \frac{1}{2} \times b \times \: h$

$= \frac{1}{2 } \times 10 \times 10$

$= \frac{1}{2} \times 100$

$= 50 {cm}^{2}$
