Step-by-step explanation: start by using the formula for area of a triangle: A =bh/2 and plug in values given for the larger triangle to find the height. 115=9h/2,. 230 =9h h= 25.556
Subtract from perimeter to get an estimate of the third side: 62-34.556=27.45
Realize now that the drawing is not to scale!
Use the dimensions of the larger triangle to and the proportion 6.7/9 = smaller / larger to find other dimensions of the smaller triangle. Add the sides to get perimeter. Multiply bh/2 to get the Area. Choose the answer that is closest to your calculations as the numbers are estimated. We cannot assume that this is a right triangle.
