Question

Please help--

Area of triangle PQR = 10.2 square units

Area of triangle PRS = 11.5 square units

Area of triangle PST = 16.3 square units


The area of Figure PQRST is

square units. (Input whole number only.)

Answer 1

The area of
`PQRST` equals to the sum of areas of the triangles it consists of. So,

`A(\mathrm{PQRST})=A(\mathrm{PQR})+A(\mathrm{PRS})+A(\mathrm{PST})=10.2+11.5+16.3=\boxed{38}`
