16.5 inches²

300

Base 6

height 3

18 units²

400

Find the Perimeter

24inx76in  (NO CALCULATOR)

200 inches

500

Find the error.               Wrong.Base 500meters

Find the perimeter         Height 600meters

The Base is 600 meters   Wrong answer 1100

The Height is 500 meters

The wrong part is the answer they were 1100 off

Area of Triangles

100

What is the formula for a triangle?

1/2*bh

200

 Find the area of the Triangle.

13ft is bottom 

14ft is slanted line

16ft is dotted line in the middle

The answer is 104ft²

300

Find the shaded region.

triangle=

Slanted line=7m

dotted line=8m

Base=10m

Shaded region=3x4m

28m²

400

Find the perimeter.

Base=20mi

slanted line=19mi

Slanted line=19mi

58mi

500

Find the error 

base:10m

Height:12m

slanted line:13m     =65m²

=60m²

The side length of 13 meters was used instead of the height.
