Question

find the area and perimeter ​

Answer 1

Answer:

given is a triangle: with hight 4cm & sides 5cm

and a semi circle:with 4.2 diameter

the perimeter of the triangle: side + base + side

: 5+4.2+5

: 14.2

the circumference of a circle : πr

3.14 × (4.2 /2) 2.1

and then divide because it is the semi circle

: 3.297

now add them : 14.2 + 3.297

and sub 4.2 to find the whole perimeter

the perimeter is : 13.297

sorry I don't know the area
