(2-)area=98sq cm,b=4cm find length
(3-)Area=390,b=13cm,find length

Answer 1

Answer:

here you go

1. the figure is a square

area = 289 sq cm

area = s x s x s

area = s²

289 = s²

√289 = s

s = 17 cm

2.  the figure is a rectangle

area = 98 sq cm

  breath = 4 cm

area = l x b

98 = l x 4

98/4 = l

l = 24.5

3. the figure is a rectangle

area = 390 sq cm

b = 13 cm

area = l x b

390 = l x 13

390/13 = l

l = 30 cm
