area of a upper rectangle =l×b
=28 ×45
=1260 cm2
In right angle triangle
let us take that right angled at B and the upper would be A and the down would be C
then,
AC2=AB2+BC2
=(28)2 +(21)2
=784 + 441
AC2=1225
therefore,
AC= ROOT OF 1225
=35 cm
therefore,
area of a right angled triangle=1/2×b×h
=1/2×21×28
=294 cm2
Area of down rectangle =l×b
=21×40
=840 cm2
In the semi-circle,
radius=diameter/2
=35/2
=17.5 cm
therefore area of a semi circle=pi×r2/2
=22/7×17.5×17.5/2
=481.5 cm2
Then you can add all the areas to find the total area.,thanx for the patience and mark me as brainliest if its correct .,,thank you
