Question

describe how the given changes to the dimensions of the figure will affect its perimeter or area. what happens to the perimeter of a rectangle with length 29 units and width 18 units when its dimensions are increased by 10 units? > move an answer into each space provided. the perimeter of the resulting rectangle will be increased by 10 by 40 by a factor of 10 by a factor of 100

Explanation:

Step1: Recall perimeter formula

The perimeter formula of a rectangle is $P = 2(l + w)$, where $l$ is length and $w$ is width. The original length $l_1=29$ and width $w_1 = 18$, so the original perimeter $P_1=2(29 + 18)=2\times47 = 94$.

Step2: Calculate new dimensions

The new length $l_2=29 + 10=39$ and new width $w_2=18 + 10 = 28$.

Step3: Calculate new perimeter

The new perimeter $P_2=2(39+28)=2\times67 = 134$.

Step4: Find the change in perimeter

The change in perimeter is $P_2 - P_1=134 - 94 = 40$.
