Answer:
Yes, Rain is correct
238.5 square inches
Step-by-step explanation:
Surface Area of a Triangular Pyramid,A = 1/2(a × b) + 3(1/2 × b × s)
= (1/2 × 10 × 8.7) + 3(1/2 × 10 × 13)
= 43.5 + 3(65)
= 43.5 + 195
= 238.5 square inches
The surface area of the triangular pyramid = 238.5 square inches
Set it up as a ratio: 1/m = 2/m+7 and cross-multiply to get m+7 = 2m. Now solve
