Answer:
20 inches
Step-by-step explanation:
To solve this problem, we need to cross multiply. Lets input the values (4, 6, 30) as shown below:
Next we cross multiply. We multiply 4 and 30, and we multiply 6 and <em>x</em>.
Now, lets put the values above back into the equation:
Our last step is to divide 120 by 6 to get <em>x </em>by itself.
The answer is 20 inches.
Answer:
48.5cm²
Step-by-step explanation:
The figure is can be divided into 3 parts:
The square, The rectangle and The triangle
We will be finding the area of each shape.
The square: Area = length * length
Length of square = 3. Area = 3 cm * 3 cm = 9 cm²
The rectangle: Area = length * breadth
Length = 8 cm; Breadth = 4 cm. Area = 8 cm * 4 cm = 32 cm²
The triangle: Area = 0.5 * height * base
Height = 5 cm; Base = 3 cm. Area = 0.5 * 5 * 3 = 7.5 cm²
Base is the shorter side of the triangle that is not the diagonal side (hypotenuse). It is gotten by subtracting the given length of the bottom part of the figure which is 4 cm from the top part of the figure which is 7 cm and it is also the other side of the square that is not given.
Height is the longer side of the triangle that is not the hypotenuse.
It is gotten by subtracting the given length of the right side which is 3 cm from the given length of the left side of the figure which is 8 cm.
Base and height can be used interchangeably.
Adding all the areas together: 9 + 32 + 7.5 = 48.5 cm²

A= 2(wl+hl+hw)
A= 2(3x4+0.5x4+0.5x3)=31
