Step 3 Do the operations to get a number answer
Step 4 Add units to your answer
(example for area: cm², inches²)(example for volume: cm³, inches³, feet³)

Answer 1

so as i draw for the triangle we solve it by:

b=base=4m

h=height=2m

A=1/2bh

=1/2(2m)(4m)

= 4 squer meter

for the rectangle we calculate Area and perimeter by

A =l×w

=3cm×5cm

=15 squere centimeter

P= w+w+l+l

=2w+2l

=2(3cm)+2(5cm)

=6cm+10cm

=16cm

for the squere:

s = 7 inch so wecan calculate area and perimeter by

A = s^2

=(7in)^2

= 49 squere inch

P= 4s

=4(7in)

=28inch
