Unit 4, Lesson 13

Rectangles with Fractional Side Lengths

Grade 6

Practice

Problem 1
Student Task Statement
Find the unknown side length of the rectangle if its area is 11 m². Show your reasoning.

A rectangle that has area labeled 11 meters squared. The side length of one side of the rectangle is labeled three and two thirds meters and the side length of the other side is labeled with a question mark. Each angle has a right angle symbol indicated.

Check your answer by multiplying it by the given side length (). Is the resulting product 11? If not, revise your previous work.
