Question

I need help with math question. It is put in a picture Number 93

Answer 1

ANSWER

• Perimeter: 34 cm

,

• Area: 48 cm²

EXPLANATION

The perimeter of a polygon is the sum of all of its side lengths. The perimeter of this trapezoid is,

$P=5cm+15cm+5cm+9cm=34cm$

The area of a trapezoid is,

$A=\frac{b+B}{2}\cdot h$

Where b and B are the bases, and h is the height,

$A=\frac{15cm+9cm}{2}\cdot4cm=48cm^2$

Hence, the perimeter is 34 cm and the area is 48 cm².
