step by step explanation ​

Answer 1

Answer:

the answer is 360cm²

Step-by-step explanation:

Area of rectangle: L × B

= 10 × 24

= 240cm²

Since the opposite sides of the triangle are equal, the base of the triangle EC is 10cm.

now, the height can be found by using the pythagorous therom as it is a iscoseles triangle.

now we are using half of the triangle to find the height , so the base becomes 5cm

pythagorous theorem:

A²+B²=C²

A²+5²=13²

now we have to find the A², the height

so,

A²= 13²-5²

A²= 169-25

A²= 144

A= root 144( the square root of 144 is 12)

so A, the height = 12

area of the triangle:

1/2 × B×H

1/2×10×12

that is 60cm

the total area : are of the reactangle+ area of the traingle+ the area of other triangle

that is,

240+60+60= 360cm²
