Answer:

Total Perimeter = 30 in

Total Area: 30 in²

Explanation:

First, do the perimeter of the triangle.

Equation: side+side+base = 3 + 4 + 5 = 12

Next is the perimeter of the rectangle.

Equation: 2(length + width) = 2·(5 + 4) = 18

Then, add the two perimeters:

12 + 18 = 30 in (Total Perimeter = 30 in)

Next, do the area of the triangle.

Equation: height • base/2 = 4 · 5/2 = 10

Finally, the area of the rectangle.

Equation: width • length = 4 · 5 = 20

Then, add the two areas:

10 + 20 = 30 (Total Area: 30 in²)

Answer:

Perimeter= 20 inches

Explanation:

since the perimeter of a plane figure is distance round the shape, we add all the sides in order to get 20inches.

Perimeter= 4+5+4+4+3= 20incjes. That's for the perimeter.

Then area, we divide the shape into two portions sides A and B.

We find the area of side A which is a rectangle so, the are = Length×Breadth..

= 4×5 = 29cm².Side B is a triangle so it's area will be
