Answer:
Perry is correct, she covered the greatest area = 18 square units.
Step-by-step explanation:
Looking at the attached diagram, the shapes are rectangular and they are on grid or graph
Note that on a graph:
1 square box = 1 unit
Area of rectangle = Length × Width
For Karina
The Width = 3 units
The length = 4 units
The area which Karina covered = 3 units × 5 units
= 15 square units
For Perry
The Width = 9 units
The length = 2 units
The area perry covered = 9 units × 2 units
= 18 square units
Therefore, Perry is correct, she covered the greatest area = 18 square units.

1st. 34 sq. inch
2nd. 40 sq. m
Step-by-step explanation:
for first figure,
i divide it into rectangle and triangle
rectangle = l×b = 7×4 = 28
triangle = 1/2× b×h = 1/2 × 3× 4 = 6
total= 28+6=34 sq.inch
for second figure,
I divide it into a square and two rectangles
square = 3×3= 9
1st rectangle= 4×7=28
2nd rectangle= 3× 1 =3
Total = 40 sq.m
