Answer:
Area: 133
Perimeter: 45 units
Step-by-step explanation:
to find b you would add up 7+5=12.
b=12
To find a you would most likely add up 7+7=14.
a=14.
To find the perimeter add up 7+7+5+12+14=45units.
To find the are you could time 7*7=49 and 7*12=84.
then you would add the two numbers to get that the area is 49+84=133.
