1 cm
2 cm
What is the area of the
composite figure?
cm
8 cm

Option D is correct.Step-by-step explanation:We are given with a solid figure with cuboid in base and square based pyramid in top.we have to find Surface of the figure.Surface Area = Curved surface ares of cuboid + area of base of cuboid + lateral surface area of pyramid.Length of the cuboid, l = 8 cmwidth of the cuboid , w = 8 cm height of the cuboid , h = 11 cm Lateral surface area of pyramid = 4 × Area of a triangle Base of triangle , b = length of cuboid = 8 cmHeight of the triangle ,H = 8 cmSurface Area = 2 × h × ( l+w ) + l × b + 4 × 1/2 × b × H                       = 2 × 11 × ( 8 + 8 ) + 8 × 8 + 2 × 8 × 8                       = 22 × 16 + 64 + 128                       = 352 + 192                       = 544 cm²Therefore, Option D is correct. Step-by-step explanation:

my answer got deleted but it's a

step-by-step explanation:

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
