Answer 2

Step-by-step explanation:

$\Huge\red{\mathfrak{ Answer }}$

Total surface area of prism= Area of 2 right angled triangle + area of parallelogram + Area of 2 rectangles

First

Area of 2 triangle = 1/2* base*height

= 1/2*21*20= 21*10= 210 cm ^2= 2*210= 420 cm^2

Area of parallelogram

= base *height= 20* 21cm= 420 cm^2

Area of 2 rectangles = lengths *breadth

= 21* 22= 21(20+2)= 420+42= 462= 462*2 = 924 cm^2. (2 rectangles)

total surface area = 924+420+420= 924+ 840= 1764cm^2

hope it helps ✌
