If the perimeter of a rectangular garden is 600 m, its length when its breadth is 100 m is________?
Correct answer: C. 200 m
- A. 650 m
- B. 600 m
- C. 200 m
- D. 300 m
Explanation
The perimeter equation is 2(L + B) = 600 m. Substituting B = 100 m gives 2(L + 100 m) = 600 m, so L + 100 m = 300 m and L = 200 m. Option d, 300 m, is the value of L + B rather than the length alone.

About Area and Volume
Area measures the surface enclosed by two-dimensional figures, while volume measures the space occupied by three-dimensional solids. Problems use formulas for rectangles, triangles, circles, prisms, cylinders, cones, spheres, and composite figures, including unit conversion and the distinction between surface area, lateral area, and volume.
