Answer:
4 cm
Step-by-step explanation:
Both the area of a square and the area of a rectangle can be found by multiplying length x width. Because all of the sides of a square are equal, you get 64 when you multiply two sides together to find the area.
Since the rectangle has the same area as the square, that means the rectangle's width has to be a number that equals 64 when multiplied by 16.
So, 64/16 equals 4.
Please mark as brainliest ;)
We can divide the shape into a rectangle and a triangle:
(1) Area of rectangle = length*width
From the graph we can see that the length of the rectangle is 7 units and the width is 5 units
Area = 7*5 = 35 units^2
(2) Area of triangle = 1/2*bh
From the graph we can see that the base of the triangle is 4 units and its height is 5 units
Area = 1/2*4*5 = 10 units^2
(3) Total area = area of triangle + area of rectangle
= 10 + 35
= 45 units^2
