the length of a rectangle is twice the breadth. If the perimeter is 60m, find its ara

Question

Eva · Answer

Length = 2Breadth    Perimeter = 2(Length + Breadth)  60 = 2(3 Breadth)  6 * Breadth = 60  Breadth = 10 m  Length = 20 m

Answer:   First we have to make our mathematical sentence from the data provided to figure the width which we will call X. We will use X for width (breath) and use 2X for length since length is twice the length of width. We also know there is 2 lengths and 2 widths to equal the perimeter.    Our sentence will be as follow: 2(2X)+2(X)=60m. Lets start working the sentence to find X.    2(2X)+2(X)=60    4X+2X=60    6X=60 now we divide each side by 6.    6X/6=60/6    X=10 now lets prove X=10    2(2X)+2(X)=60    2(2×10)+2(10)=60    2(20)+2(10)=60    40+20=60    60=60    so X is equal to 10
