-5
Yes, the square root of 225 is ± 15 because 15 x 15 = 225 AND -15 x -15 = 225
The perimeter of this square measures 4 x 1 = 4 decimeters. As 1 decimeter = 10 centimeters then 4 decimeters = 4 x 10 = 40 centimeters.
A is a perfect square trinomial, so first you factor it:A = (x-15)(x-15)This is a square with one side being (x-15).So the perimeter must be (x-15)+(x-15)+(x-15)+(x-15) because a square has four sides.So P = 4x-60
If you mean that the sum of the two numbers is 20 and the product is 75, then X+Y=20 and XY=75 solving for Y and substituting: Y=20-X and XY=X(20-X) then X(20-X)=75 and 20X-X2=75 (20X-X2)-(20X-X2)=75-(20X-X2) then X2-20X+75=0 factoring (X-5)(X-15)=0, so X=15 or X=5 if X=5, then Y=75/X=15 if X=15, then Y=75/X=75/15=5
15" x 10" = 967.74 square centimeters.
20 x 15 = 300 square feet
200 square cm (cm2). To calculate square centimeters simply multiply length by width - the result is the area in square cm.
If it's 12 x 14 x 15, it's not a cube. The surface area of the object is 1116 square centimeters.
15 x 20 is 300 square feet or 100 square yards.
A = L x W 20 = 10 x W 20/10 = W 2 = W

15 centimeters = 5.90551181 inches20 centimeters = 7.87401575 inchesSo 5.90551181 by 7.87401575
Easy to do. Just multiply the two dimensions: 15 x 20 = 300 square feet.
15 x 20 = 300 square feet.
There are approximately 129 square centimeters in 20 square inches.
No. 15-ft x 20-ft = 300 square feet. The 34 square feet you have only covers about 11% of it.
