Question

what is the area of a right triangle 4 centimeters high with a base of 7 centimeters?
a 14 square cm
b 28 cm
c 11 square cm
d 14 cm

Explanation:

Step1: Recall the formula for the area of a triangle

The formula for the area of a triangle is $A = \frac{1}{2} \times base \times height$.

Step2: Identify the base and height

Here, the base is 7 cm and the height is 4 cm.

Step3: Substitute the values into the formula

Substitute base = 7 and height = 4 into the formula: $A = \frac{1}{2} \times 7 \times 4$.

Step4: Calculate the area

First, multiply 7 and 4: $7 \times 4 = 28$. Then, multiply by $\frac{1}{2}$: $\frac{1}{2} \times 28 = 14$. The unit for area is square centimeters.

Answer:

A. 14 square cm
