The area of rectangle is : 20.0
By length u mean???? diagonal or height.... it doesnt have length If you meant all the lengths of the sides- the area would be 4A (the area (A) times by four).
4a square
4a*4a*4a = 64a3 cubic units

Area of a square = side2 Square A area = a2 Square B area = (4a)2 (4a)(4a) = 16a2 The area of square B is sixteen times the area of square A. Proof: Side of square A = 2 inches Side of square B = (4*2) = 8 inches Area of A = 22 = 4 square inches Area of B = 82 = 64 square inches 64 / 4 = 16
Area = base * height = 5*(4a + b) m2 = (20a + 5b) m2
You have to multiply base x height - in this case, you obtain (4a)(2a+b). This can't be simplified; you can leave it as it is (factored), or multiply it out to obtain 8a2 + 4ab.
Area of the rectangle = 36 =Length * Width Assume Width= a Hence Length = 4*a =4a Area = a*4a =36 Therefore, a*a =9 Hence a =3 =Width

We can calculate the lateral are of a prism, L.A., if we multiply the perimeter of the base, p, by the height, h. So, L.A. = pH. Since the base of the prism is a square, we can write for perimeter, p = 4a. So, L.A. = pH L.A. = (4a)h We know that: L.A. = 100 m^2 h = 5 m So, we have: L.A. = (4a)h 100 m^2 = 4(a)5 m 100 m^2 = 20a m 5 m = a Thus, the base edge is 5 m.
Area = b/4*sqrt(4a^2-b^2)a: equal sideb:third side
4a square
(4a)2 or 16a2
4a*4a*4a = 64a3 cubic units
Given the radius, the area of an circle A = πr2 Since the diameter d (which I assume is what you meant) is twice the radius, we can calculate A = π(d/2)2 A = πd2/4 4A = πd2 4A/π = d2 √(4A/π) = d 2√(A/π) = d (above, √ means square root)
What is the additive inverse of -4a?
