Each length of the side of square B is twice the length of the side of square A. John says that this means the area of square B is twice the area of square A.
Is John right?
Justify your answer.

yes

Step-by-step explanation:

because the area of square is l² so John is righrt

Area of square= ²

Area of square A= ²

Area of square B = ?

let the length of square A = x

Area of square A =x²

then the length of square B = 2x

Area of square B =2x²

x²means area of square A

so Area of square B =2 times area of squarf A

it would be 6xy and -16xy.

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
