Question

1. find the area and perimeter of the figures below. be sure to show all your work and label your answers. a) area: perimeter: formula: a = 1/2bh 6 mm 4 mm 8.5 mm 12 mm

Explanation:

Step1: Calculate the area

Use the formula $A=\frac{1}{2}bh$. Here, $b = 12$ mm and $h=4$ mm.
$A=\frac{1}{2}\times12\times4$
$A = 24$ mm²

Step2: Calculate the perimeter

The perimeter $P$ of a triangle is the sum of the lengths of its sides. The side - lengths are 6 mm, 8.5 mm and 12 mm.
$P=6 + 8.5+12$
$P = 26.5$ mm

Answer:

area: 24 mm²
perimeter: 26.5 mm
