Answer:

Step-by-step explanation:

let width=x

length=3x

area=x*3x=3x^2

so 3x^2=10

$x=\sqrt{\frac{10}{3} } \\width=\sqrt{\frac{10}{3} } \\length=3*\sqrt{\frac{10}{3} } =\sqrt{30}$

Answer:

58 cm

Step-by-step explanation:

if both shapes are squares, then the perimeter must be divide by all 4 equal sides

36 / 4 = 9, so each side of the first shape is 9 cm

40 / 4 =10 , so each side of the second shape is 10 cm

by putting the shapes together two of the side seal 1 side of each shape but 10-9 is 1 so add all three sides of the rest of the shape,

so 9+ 9+ 9= 27, then the three side of the second shape,

so 10+ 10+ 10= 30, then that extra 1 cm of difference from the size difference when put together,

so 27+ 30+ 1= 58 cm
