Question

solve.
4 what is the area of the triangle at the right?
diagram: a triangle with base labeled 7 ft and height (dashed right - angled lines) labeled 10 ft
$a = \frac{1}{2}b$ ____
$= \frac{1}{2} \times 7 \times$ ____
$=$ ____
the area is ____ square feet.

Explanation:

Step1: Identify base and height

Base \( b = 7 \) ft, height \( h = 10 \) ft.

Step2: Substitute into area formula

Area of triangle \( A=\frac{1}{2}bh \), so \( A = \frac{1}{2} \times 7 \times 10 \).

Step3: Calculate the product

\( \frac{1}{2} \times 7 \times 10 = \frac{70}{2}=35 \).

Answer:

The area is \( 35 \) square feet.
