Question

area is the space covered by a shape. to calculate area, you will need the following formulas:

Explanation:

Step1: Recall triangle area formula

The area formula for a triangle is $A=\frac{1}{2}bh$, where $b$ is the base and $h$ is the height.

Step2: Recall rectangle area formula

The area formula for a rectangle with length $l$ and width $w$ is $A = lw$.

Step3: Recall parallelogram area formula

The area formula for a parallelogram with base $b$ and height $h$ is $A=bh$.

Step4: Recall trapezoid area formula

The area formula for a trapezoid with bases $a$ and $b$ and height $h$ is $A=\frac{(a + b)h}{2}$.

Answer:

For triangle: $A=\frac{1}{2}bh$; For rectangle: $A=lw$; For parallelogram: $A = bh$; For trapezoid: $A=\frac{(a + b)h}{2}$
