What is the perimeter of this rectangle? a. 21 ft b. 42 ft c. 44 ft d. 68 ft

Note that this shape is a rectangle, so the opposite sides have the same measurements.

Note that to solve for perimeter, you must add all sides together:

4 + 4 + 17 + 17 = 42

B.  42 ft is your answer

hope this helps

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
