13(n + 4 + 7m)
= (13) (n+4+7m)
= (13) (n) + (13) (4) + (13) (7m)
= 13n + 52 + 91m
= 91m + 13n + 52

Answer:
Surface area of net = 310 cm²
Step-by-step explanation:
Given:
Dimension of two same rectangle = 11 cm by 9 cm
Dimension of single rectangle = 11 cm by 7 cm
Height of two triangle = 5 Cm
Base of two triangle = 7 Cm
Find;
Surface area of net
Computation:
Surface area of net = Surface area of two same rectangle + Surface area of single rectangle + Surface area of two same triangle
Surface area of net = 2[l x b] + [l x b] + 2[(1/2)(b)(h)]
Surface area of net = 2[11 x 9] + [11 x 7] + 2[(1/2)(7)(5)]
Surface area of net = 198 + 77 + 35
Surface area of net = 310 cm²
