Construct a rectangle whose one side is 3 cm and a diagonal equal to 5 cm.​
VMariaS [17]

Answer:

Length = 4 cm

Breadth = 3 cm

Step-by-step explanation:

Its Simple, We use The Pythagoreas theorem,

We know that the Hypotenuse of a triangle squared is equal to the sum of the legs square,

So  A^2 + B^2 = C^2

substitute the values,

    3^2 + B^2 = 5^2

     9 + B^2 = 25.

Subtract 9 from both sides

    B^2 = 25 - 9

    B^2 = 16

     B = sqrt[16] = 4

I am assuming that you are not asking for an actual construction of a rectangle on paper, but if you are, just ask

Vivian is working with a Styrofoam cube for art class. The length of one side is 5 in. How much surface area does Vivian have to
Sphinxa [80]
The answer is 150in squared. 

Because the SA of one side is 5*5 which is 25, and since all of the sides are equal and there are six sides you multiply 25 by 6, which equals 150.
