ABCD and EBFC are rectangles.
Calculate the perimeter of the rectangle ABCD.
Since every pair of opposite sides are equal to each other in a rhombus, we know that:
To calculate side AB, we must use the following formula:
As we are only given the length of EB, we don't have enough information and cannot calculate the lengths of the other sides.
Not enough data
Look at the rectangle ABCD below.
Side AB is 6 cm long and side BC is 4 cm long.
What is the area of the rectangle?
The measurements 5 and 3 are from rectangle EBFC, not the complete rectangle ABCD. To find the perimeter of ABCD, we need to know all four sides of rectangle ABCD.
'Not enough data' means we cannot solve the problem with the given information. Even though rectangles have predictable properties, we still need sufficient measurements to calculate unknown values.
For rectangle perimeter, you need either:
Looking at this problem, there's no way to determine AE from the given information. The diagram shows two rectangles sharing some sides, but AE is not given or calculable from segments 5 and 3.
First, list what you know and what you need to find. Then check if you can calculate the missing values. If not, 'not enough data' is likely the correct answer - don't guess!
