C  459cm2

Step-by-step explanation:

You multiply the area of the square first and add that to the area of the two right triangles.

Area of the square - Bh = 22(18) = 396

Area of ONE right triangle - 1/2bh    h = 7    b = the base of the triangle

Look at the bottom of the square (18 cm) and divide that by two to get the base of the triangle

1/2(9)(7) = 31.5

Area of BOTH right triangles - 31.5(2) = 63

Total Area - Then you add 396 to 63 and you get 459 cm2, or C, which is the answer

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
