What is the perimeter of this quadrilateral?
18 + 18 + 20 + 32
36 + 20 + 32 = 88mm
Find the perimeter:
12 x 5 = 60cm
or
12 + 12 + 12 + 12 + 12 =60
Find the Area
20 x 32 = 640 meters squared
The perimeter is 56m. If the length is 16 m, what is the width?
16 + 16 = 32
56-32= 24
24/ 2 =12m
Find the missing length of this quadrilateral:
Perimeter is 30cm
Width is 6cm
What is the length?
6 + 6 = 12
30 -12 = 18
18 / 2 = 9cm
