Math Problem Statement

solve

Find the area of the given shape, which is a combination of a rectangle and a triangle.

Solution

To find the area of the shape, we can split it into two parts:

  1. A rectangle (the bottom portion).
  2. A triangle (the slanted portion at the top).

Step-by-step solution:

1. Find the area of the rectangle:

The rectangle's dimensions are:

  • Height = 7cm7 \, \text{cm},
  • Base = 8cm8 \, \text{cm}.

The area of the rectangle is: Area of rectangle=base×height=8×7=56cm2.\text{Area of rectangle} = \text{base} \times \text{height} = 8 \times 7 = 56 \, \text{cm}^2.

2. Find the area of the triangle:

The triangle has:

  • Base = 8cm8 \, \text{cm} (the same as the bottom of the rectangle),
  • Height = 6cm6 \, \text{cm} (perpendicular from the top to the base).

The area of a triangle is given by: Area of triangle=12×base×height.\text{Area of triangle} = \frac{1}{2} \times \text{base} \times \text{height}.

Substitute the values: Area of triangle=12×8×6=24cm2.\text{Area of triangle} = \frac{1}{2} \times 8 \times 6 = 24 \, \text{cm}^2.

3. Total area:

Add the areas of the rectangle and triangle: Total area=56+24=80cm2.\text{Total area} = 56 + 24 = 80 \, \text{cm}^2.

Final Answer:

The total area of the shape is 80cm280 \, \text{cm}^2.
