Area of a rectangle using diagonal and height?

Use the Pythagorean Theorem (a2 + b2 = c2, where a and b are the legs and c is the hypotenuse) and then you will know the base of the rectangle (which would be a or b, depending on which you use). Then you can multiply the base and height to find the area of the rectangle!Great answer!


Find the Area b 24 and h 10 what is Area?

If those are the dimensions of a rectangle, simply multiply length times width.


If sides of rectangle A to rectangle B has ratio 4 to 5. What would the perimeter of rectangle A if the rectangle B has a perimeter of 100 What about area of Rectangle A if the area of rectangle B is?

The perimeter of rectangle A would then be 80 because 80 to 100 is 4 to 5 simplified and the area of triangle A would depend on the sides and area of rectangle B which have not been given.


What is the formula for finding the area of a rectangle?

How does finding the area of a parallelogram relate to finding the area of a rectangle?

Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply.


The formula for the area of a rectangle with length equals b and width equals h is A equals?

A = bh (multiply length x width).

Find the area of a rectangle that has a base of 4a cm and a height of 2a plus b cm?

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.
