Question

plsssssssssssssss tell me this answer with explanation​

Answer 1

Answer:

1. l = 320 m²/16m = 20 m

2. 70 = 2[28+b]

   35 =28+b

    b= 35-28=7 cm

    area = 28 ×7= 182 cm²

3.  84 = 4l or 4b [∵ all sides are equal ]

     l = 84/4 = 21 m

      b = 21 m

4. 2[50+20] = 140 mm

5. b = 4 mm [ ∵ all sides are equal in a square ]

    perimeter = 4l = 4[4] = 16 mm
